Answer to Question #172550 in Physics for Diocos

Question

The bulk modulus of material is 3.72 × 10¹¹ N/m₂. What fractional change in volume does a piece of this material undergo when it is subjected to a bulk stress increase of 8.46x10⁷ N/m²? Assume that the force is applied uniformly over the surface

Answer 1

$\frac{\Delta V}{V}=\frac{\Delta p}{B}\\\frac{\Delta V}{V}=\frac{8.46\cdot10^{7}}{3.72\cdot10^{11}}=2.27\cdot10^{-4}$
